Man the last part of the title is correct. It has become an obsession. However this obsession has found the granddaddy of all antenna radial documents.
Ground Systems As A Factor In Antenna Efficiency by GH Brown, RF Lewis and J Epstein ( RCA Engineers) the PDF can be found here: https://www.qsl.net/hiarc/Files/George%20brown%20RCS%20radials.pdf
This document was most enlightening. When used in conjunction with the Rudy Stevens N6LF study from QEX, as mentioned in Radials 3, is a very complete study of radials and their place. These documents should be required reading for builders, makers, and installers of vertical radios. I will be reading them again and again, and looking for other original investigations including my own.
My current experiment is using a WRC (Wolf River Coils) vertical with 15 x 5 meter radials checking for lowest swr. reactance and resistance ( think that’s what I need to measure). The problem is I only have the 817nd for portable use, I need another radio or to trade the 817 for a 891.
